NE70BK00 is Canyon’s standard 70 Shore A black Neoprene (CR) compound developed for general-purpose O-rings and gaskets used in industrial and HVAC sealing applications. This cost-effective material offers good resistance to weathering, moderate heat, and low-temperature solvents and refrigerants, supporting dependable sealing performance across a wide range of environments. With a service temperature range of -40°C to 121°C (-40°F to 250°F), NE70BK00 maintains elasticity and sealing integrity in static and light dynamic applications. Its balanced durometer provides a practical combination of durability and conformability for everyday sealing needs. Compare NE70BK00 to Parker C0873-70 and C0557-70 for similar 70 Shore A Neoprene sealing performance.
NE70BK00 meets ASTM D2000 M3BC710 requirements and is commonly used in pumps, valves, enclosures, and general machinery where reliable Neoprene performance and cost control are important. This compound is frequently selected when environmental resistance and refrigerant compatibility are required without moving to higher-cost specialty elastomers. Canyon Components offers NE70BK00 as a dependable solution for standard Neoprene O-rings and gaskets across many industrial sealing applications.
